Nautilus is a kind of aquatic creature often grouped with fish in simple classifications. In a similar way, Teal is a specific type of which bird?

Introduction / Context:
This analogy question uses examples and their broader categories from the animal world. The pair Nautilus : Fish uses a common, simplified classroom classification where nautilus is treated as a sea animal grouped with fish, even though scientifically it is a mollusc. In the second pair Teal : ? we must decide to which group teal belongs. These questions test your general knowledge of animals and your ability to see specific example to category relationships in analogy format.

Given Data / Assumptions:

• Nautilus is a marine creature that is often broadly grouped with fish in simple reasoning questions.
• Fish is the broader aquatic animal group used in this analogy.
• Teal is a small water bird known to many people through nature and general knowledge books.
• The options we now use are Duck, Pigeon, Swan, and Chicken as plausible bird categories.
• We assume basic awareness that teal is a kind of duck rather than any other bird.

Concept / Approach:
The relationship in the first pair is that of example to broader type. Nautilus is a particular sea animal and it is grouped under fish in this simplified setting. For the second pair, we must find the broader bird type under which teal falls. In everyday general knowledge, teal is described as a small freshwater duck. Therefore the correct connection is Teal : Duck. The other birds listed as options are not correct broader categories for teal; instead they are separate bird types of their own.

Step-by-Step Solution:
Step 1: Understand that the first pair Nautilus : Fish represents a specific aquatic creature and its general group. Step 2: Recognise that the second pair must also have the pattern specific example to general category. Step 3: Recall that teal is a small waterfowl often seen on lakes and ponds and is classed as a duck species. Step 4: Examine the options: Duck, Pigeon, Swan, and Chicken. Step 5: Know that teal is not a type of pigeon, swan, or chicken but is a variety of duck. Step 6: Choose Duck to complete the analogy as Teal : Duck.

Verification / Alternative check:
We can confirm this answer by checking how teal is described in nature notes and wildlife references. They typically state that teal are small dabbling ducks. They often migrate and live in wetland environments. A pigeon is a city or farm bird that belongs to a completely different group and is not a waterfowl. Swans are large, white water birds which are quite distinct in appearance and classification from small teal ducks. Chickens are domesticated birds kept for eggs and meat and are land based rather than waterfowl. Therefore only Duck can be the correct category for teal, matching how nautilus in this question is treated as belonging to fish in a simplified manner.

Why Other Options Are Wrong:
Pigeon: Teal does not belong to the pigeon family. Pigeons are mainly land or city dwelling birds and do not match teal in lifestyle or classification. Swan: Although swans and teal both live near water, teal are small ducks, not swans. Swan is a separate kind of water bird. Chicken: Chickens are farm birds that live on land and do not belong to the waterfowl group. Teal is not a type of chicken.

Common Pitfalls:
Some candidates may be unfamiliar with the word teal and may confuse it with the colour teal instead of the bird. Remember that many colours are named after animals or plants, including teal, which is named after the coloured eye patches of the duck. Another pitfall is to think only in terms of water birds and select swan because both teal and swans live near water. However, the correct approach is to recall the exact general category for teal, which is duck. Focusing on specific example to type relationships leads directly to the right answer.

Final Answer:
Just as nautilus is treated as belonging to the group of fish, teal is a kind of duck, so Duck is the correct option.
